Christopher Tubbs commented on ACCUMULO-1255:
---------------------------------------------
Invoked with 'mvn clean verify' on a clean checkout, OpenJDK 1.6, Maven 3.0.5.
I'm not sure that it needs to be removed (I haven't looked at what it tests in
detail), but if there's some way it can be made more resilient to the relevant
timing issues, at the very least, that would help.
